DCPA-4000
The DCPA-4000 is a vehicle-only driveway alarm that uses a buried magnetic probe instead of a motion sensor. It is built for buyers who want notice of cars and trucks without constant trips from people, pets, or wildlife.

DCMA-4000
The extended range of up to 5,000 ft makes this driveway monitoring system kit perfect for large properties or businesses. The driveway sensor mounts outdoors – pointing across the area to be monitored – and the flashing chime receiver plugs into any outlet where you want to hear the chime alert. Add additional receivers to listen in multiple locations or monitor more than 1 area by adding another driveway monitor sensor. A driveway monitor alert will trigger the receiver chime when motion is detected. Choose different chime sounds for multiple alerts. Easy installation has the system operational in no time!

DCR-4000
DCR-4000 is a wireless receiver for compatible Dakota Alert 4000 Series transmitters. It is useful for warehouses, offices, shops, receiving areas, and larger properties where a standard residential receiver may not carry far enough or clearly enough.

UT-4000
The UT-4000 is a commercial-grade, wireless push button (or door contact) compatible with Dakota’s 4000 series of products. Pair the push button with the receiver, mount it on the door, and it will transmit a wireless signal up to 5000 ft. Use it as a door/window contact to alert you when the door is open. **Please note that it IS NOT compatible with the Dakota Alert 2500 series or the ERA series by Safeguard Supply.**

DCMT-4000
DCMT-4000 is a driveway alarm sensor/transmitter for compatible Dakota Alert 4000 Series receivers. It is designed for outdoor monitoring where you need notice when a vehicle or person crosses a defined approach area.

Buying notes
Is this the right fit?
- Good fit when
- Use this when you need an additional compatible sensor at a door, gate, counter, driveway, or other alert point.
- Look at another option when
- Choose a kit instead if you do not already have a compatible receiver. This transmitter sends the signal; it does not make the chime sound by itself.
- Range reality
- 5000 ft is the published open-air distance from this transmitter to a compatible receiver. Walls, metal, masonry, vehicles, shelving, and dense trees can reduce that distance.
- Setup note
- Mount the sensor where it can detect the event and where its signal can reach the receiver. Pair it to the receiver, then set the tone or zone on the receiver side.
The DCMT-4000 is a practical choice when the driveway or approach area needs an outdoor sensor that can report back to a compatible indoor receiver without requiring trenching or more involved wiring. It works with the DCR-4000 and RE-4K-PLUS receivers and is often used in residential driveways, farm lanes, commercial entries, and other approach points where longer wireless reach matters.
This sensor uses adjustable sensitivity settings, letting you set a smaller or larger detection zone depending on the driveway layout. It also includes options for the outdoor filter, LED indicator, and reset timing, which helps if you are trying to reduce nuisance triggers or keep a busy monitored area from repeating too often.

Bought 3 sensors, furthest is 1000 feet out, with some trees in the way. All seem to be going off repeatedly and reliably. Very satisfied, and reasonably priced too
Lost power 2 days ago due to the blizzard.. haven’t been able to get to fully connect everything yet but thanks for checking in on me
Great consumer support, you guys are the best.
Haven’t Installed the product, but it arrived a few days after the order was placed and appears to be intact
cannot use with my old receiver and have to order new one!
I called the customer service number and got a very helpful person who recommended exactly what I needed which was less expensive and better suited for what I needed.
